The Italian has already made his mark on the squad, bringing Jorginho with him from Napoli much to the chagrin of Manchester City.

Sarri was unveiled to the media on Wednesday, July 18, and pressed home his philosophy and how he plans to implement his ideas on his new squad.

Where are they going?

Unlike in recent years, there isn’t a commercially rewarding tour in one country. Instead, a series of fixtures will see them fly 20,000 miles. They have already arrived in Australia to play Perth Glory, before matches in Nice, Dublin and at Stamford Bridge in the International Champions Cup. The Community Shield against Manchester City will provide the real test.

Who’s going and who’s not?

The most notable name in Perth right now is £57.4million signing Jorginho, along with Cesc Fabregas, Alvaro Morata and Pedro, plus fit-again David Luiz. Keepers Thibaut Courtois and Willy Caballero are on holiday.

When are the big guns back?

All those involved in the World Cup were given three weeks off from the day after their nation was knocked out. Eden Hazard, N’Golo Kante, Olivier Giroud, Gary Cahill, Michy Batshuayi, Ruben Loftus-Cheek and Courtois will not be back until August 5-6.

What are the key issues for the manager?

Maurizio Sarri must get to know his squad, implement his own style of play and convince key personnel to stay.

Five days later and Chelsea will be back in Europe as they take on Inter Milan in the International Champions Cup in Nice. Arsenal are the opponents, again in the ICC, on August 1 as Sarri gets a look at one of his expected rivals in the Premier League for the first time.

The traditional season curtain-raiser follows four days later as the Blues take on City. Pep Guardiola was a vocal fan of Sarri's Napoli team last year.

Chelsea's final pre-season outing is at home to Lyon, Sarri's first at Stamford Bridge, and comes four days before their opening Premier League fixture of a trip to Huddersfield Town.
